Hey ufool2000, I'm a YHOO stock holder and a big fan of Yahoo, but I sincerly hope you're not using a comparison of Yahoo vs. BRK as justification for investing in YHOO. There simply is no comparison in there industries, business models, management styles, etc. Yahoo should be judged against its pears and competitors or by itself.

ufool says, "Do these points really matter ? The objective is not to compare any of the attributes you mentioned but only the appreciation of the stock value."

I think even Mr. Buffet himself would agree with you. That's probably why he owns companies from Coke to GEICO. I don't know much about it, but I would guess that YHOO's risk factor is way too high for BRK to be interested. But if we're right about YHOO, we'll get a much better return than with BRK.
